U.S. HIGHWAY VEHICLE MILES TRAVELED
Highway Vehicle Miles Traveled (monthly data, with underlying trend)
Vehicle miles of travel (VMT) are key data for highway planning and management, and a common measure of roadway use. Along with other data, VMT are often used in estimating congestion, air quality, and potential gas-tax revenues, and can provide a general measure of the level of the nation's economic activity.
| Vehicle Miles Traveled | Jun-01 | Jun-02 |
|---|---|---|
| Millions of highway miles | 242,334 | 246,385 |
| Vehicle miles percent change from same month previous year | -0.38 | 1.67 |
NOTE: The current value is compared to the value from the same period in the previous year to account for seasonality.
A trendline has been provided for vehicle miles traveled. The trend has been calculated through a statistical procedure called Structural Modeling, in which the time series under study is decomposed into seasonal, trend and irregular components. For further information on this statistical procedure, see: S.J. Koopman, et al., Structural Time Series Analyser Modeller and Predictor (STAMP), London: Timberlake Consultants Ltd., 2000
